Amundsen–Scott South Pole Station in the context of "Science and technology in the United States"

The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's axis of rotation meets its surface. It is called the True South Pole to distinguish from the south magnetic pole.

The South Pole is by definition the southernmost point on the Earth, lying antipodally to the North Pole. It defines geodetic latitude 90° South, as well as the direction of true south. At the South Pole all directions point North; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the South Pole, so any time can be used as the local time. Along tight latitude circles, clockwise is east and counterclockwise is west. The South Pole is at the center of the Southern Hemisphere. Situated on the continent of Antarctica, it is the site of the United States Amundsen–Scott South Pole Station, which was established in 1956 and has been permanently staffed since that year.

As Antarctica has never been permanently settled by humans, there has historically been little military activity in the Antarctic. The Antarctic Treaty, which came into effect on June 23, 1961, bans military activity from the continent. Military personnel and equipment may only be used for scientific research or any other peaceful purposes, such as delivering supplies.

The Antarctic Treaty specifically prohibits military activity on land or ice shelves below 60°S. While the use of nuclear weapons is absolutely prohibited, the Treaty does not apply to naval activity within these bounds (in the Southern Ocean) so long as it takes place on the high seas.

The Antarctic Plateau, Polar Plateau or King Haakon VII Plateau is a large area of East Antarctica that extends over a diameter of about 1,000 kilometres (620 mi), and includes the region of the geographic South Pole and the Amundsen–Scott South Pole Station. This huge continental plateau is at an average elevation of about 3,000 metres (9,800 ft).

The East Antarctic Ice Sheet (EAIS) lies between 45° west and 168° east longitudinally. It was first formed around 34 million years ago, and it is the largest ice sheet on the entire planet, with far greater volume than the Greenland ice sheet or the West Antarctic Ice Sheet (WAIS), from which it is separated by the Transantarctic Mountains. The ice sheet is around 2.2 km (1.4 mi) thick on average and is 4,897 m (16,066 ft) at its thickest point. It is also home to the geographic South Pole, South Magnetic Pole and the Amundsen–Scott South Pole Station.

McMurdo Station is an American Antarctic research station on the southern tip of Ross Island. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation (NSF). The station is the largest community in Antarctica, capable of supporting up to 1,200 residents, though the population fluctuates seasonally; during the antarctic night, there are fewer than two hundred people. It serves as one of three year-round United States Antarctic science facilities. Personnel and cargo going to or coming from Amundsen–Scott South Pole Station usually first pass through McMurdo, either by flight or by the McMurdo to South Pole Traverse; it is a hub for activities and science projects in Antarctica. McMurdo, Amundsen-Scott, and Palmer are the three non-seasonal United States stations on the continent, though by the Antarctic Treaty System the bases are not a legal claim (though the right is not forfeited); they are dedicated to scientific research. New Zealand's Scott Base is nearby on Hut Point Peninsula, as is Arrival Heights Laboratory. On the base is a heliport, and across the channel is a helicopter refueling station at Marble Point, but the main airfields in the 2020s are Phoenix Airfield and Williams Field which are to the south and built on ice. Winter Quarters Bay is the base seaport, though access can be limited by weather conditions when the sea ice forms. Weather can make it too hard to land aircraft, and an icebreaker may be needed to reach the port facility. However, the sea ice also makes it possible to make ice traverses and travel directly across the bay, and historically an Ice Runway was crafted. The base is powered by a mixture of generators and wind power, though it had a nuclear reactor in the 1960s.

The base was first established in the mid-1950s as part of an international program to study and explore Antarctica for peaceful purposes. Daylight is seasonal at McMurdo, corresponding to the south polar daytime, and the polar night, which is also winter, lasts from about April to September. As it warms, the sea ice melts, and the port is opened, but by about February, much of the activity drops with plunging temperatures and increasing darkness, and there are usually no flights in or out until July or August.

Concordia Research Station, which opened in 2005, is a French–Italian research facility managed by l'Institut polaire français Paul-Émile Victor and Programma Nazionale di Ricerche in Antartide, that was built 3,233 m (10,607 ft) above sea level on a geographical formation known as dôme C, on the Antarctic Plateau, Antarctica. It is located 1,100 km (680 mi) inland from the French research station at Dumont D'Urville, 1,100 km (680 mi) inland from Australia's Casey Station and 1,200 km (750 mi) inland from the Italian Zucchelli Station at Terra Nova Bay. Russia's Vostok Station is 560 km (350 mi) away. The Geographic South Pole is 1,670 km (1,040 mi) away. The facility is also located within Australia's claim on Antarctica, the Australian Antarctic Territory.

Concordia Station is the third permanent, all-year research station on the Antarctic Plateau besides Vostok Station and the Amundsen–Scott South Pole Station (U.S.) at the Geographic South Pole. It is jointly operated by scientists from France and Italy and regularly hosts ESA scientists.

The IceCube Neutrino Observatory (or simply IceCube) is a neutrino observatory developed by the University of Wisconsin–Madison and constructed at the Amundsen–Scott South Pole Station in Antarctica. The project is a recognized CERN experiment (RE10). Its thousands of sensors are located under the Antarctic ice, distributed over a cubic kilometer.

Similar to its predecessor, the Antarctic Muon And Neutrino Detector Array (AMANDA), IceCube consists of spherical optical sensors called Digital Optical Modules (DOMs), each with a photomultiplier tube (PMT) and a single-board data acquisition computer which sends digital data to the counting house on the surface above the array. IceCube was completed on 18 December 2010.
